3M E-43223 2" Aluminum Oxide Surface Discs, Roloc Style, 80 Grit (25/Box)
40% Faster Material Removal - 3M Professional Aluminum Oxide Surface Discs (E-43223, 25-Pack)
80 Grit Quick-Change Grinding Discs for Metal Preparation and Finishing
These 2-inch aluminum oxide surface discs solve the biggest problem in metal fabrication by delivering 40% faster material removal rates while reducing disc changes by 60% compared to economy alternatives. Built with premium aluminum oxide abrasive that stays sharp 3x longer and 3M's proven Roloc attachment system rated for 25,000 RPM operation, they deliver fast, controlled material removal on steel, stainless, and aluminum without the chatter or loading issues that plague cheaper grinding discs. Professional fabricators report 25% time savings per project when using quality abrasives that maintain cutting performance throughout demanding applications.
Perfect for fabrication shops, automotive repair, and general metalworking where quality and speed matter more than saving money on inferior abrasives that burn out quickly.
Key Features & Benefits
| Feature | Benefit |
|---|---|
| Roloc Quick-Change System | Type R backing system enables disc swapping in under 5 seconds without tools, eliminating fumbling with nuts and washers during high-volume jobs. The twist-lock mechanism provides secure attachment that won't slip during aggressive cutting, while the quick-change design reduces downtime by 75% when switching between grits or replacing worn discs in tight spaces. |
| Premium Aluminum Oxide Grain | High-quality aluminum oxide abrasive stays sharp longer and cuts cleaner with 30% less pressure required than standard alternatives. The advanced grain structure runs cooler during operation, preventing heat damage on thin materials, while maintaining consistent cutting performance through extended use cycles that outlast economy discs by 200%. |
| Professional 25000 RPM Rating | Engineered for high-speed operation on die grinders up to 25,000 RPM without vibration or balance issues that can damage tools or create safety hazards. Each disc maintains structural integrity and cutting performance through multiple jobs, making them cost-effective for professional fabrication environments where reliability and consistent results are essential. |
| 80 Grit Optimal Performance | Medium-aggressive 80 grit specification provides ideal balance between material removal rate and surface finish quality for most metalworking applications. Perfect for weld cleanup, rust removal, and surface preparation tasks that require controlled cutting action without excessive roughness, eliminating the need for multiple grit progressions in many applications. |
| Bulk Pack Professional Value | Twenty-five disc quantity ensures consistent supply for extended projects while reducing per-unit costs by 35% compared to individual purchases. Bulk packaging prevents inventory shortages during critical jobs, while individual disc protection maintains quality and prevents contamination, making it ideal for busy fabrication shops and contractor operations. |

Frequently Asked Questions
How does this compare to cheaper aluminum oxide discs?
3M discs use premium aluminum oxide that stays sharp longer and cuts cooler than economy alternatives. While cheaper discs may seem like a bargain, they often load up with material, lose cutting ability quickly, and can create heat damage on thin metals. These professional-grade discs actually save money by lasting longer and working more efficiently.
Will these work on my die grinder?
Yes, these discs are designed for die grinders with Roloc or Type R quick-change systems. They are rated for speeds up to 25,000 RPM, which covers most standard die grinders. The quick-change system makes swapping between grits fast and easy during multi-step finishing processes.
What is the difference between 80 grit and finer grits?
80 grit provides medium-aggressive cutting action, perfect for initial surface prep, weld cleanup, and removing moderate rust or paint. It leaves a finish that is smooth enough for most applications but aggressive enough to remove material efficiently. For final finishing, follow with 120 grit or finer.
Are these suitable for stainless steel work?
Yes. These aluminum oxide surface discs work well on stainless steel, carbon steel, and aluminum. The aluminum oxide abrasive does not load up as easily as some other abrasive types, maintaining cutting performance even on tougher alloys.
